Abstract: A security electronic file processing method based on a block chain structure is proposed by the present disclosure, including: constructing a security electronic file generation request based on an occurrence of a trigger event by a member node in a block chain formed by a master node and at least one member node, and transmitting the security electronic file generation request to the master node, wherein the master node and each of the at least one member node, each as independent block respectively, are connected to each other; generating a security electronic file by the master node based on the received security electronic file generation request, and transmitting the generated security electronic file to the member node specified by the security electronic file generation request; and performing operations on the security electronic file by any of the at least one member node after receiving the security electronic file by performing data communication with another member node. The system and method disclosed by the invention has high data file processing efficiency and low cost.

Abstract: The present invention provides a resource file processing method based on a blockchain structure. The method includes a member node in a blockchain including at least one supervision node and at least one member node constructs a resource file registration request according to a user instruction, and sends the resource file registration request to one of the at least one supervision node. According to the resource file registration request from any member node, the at least one supervision node audits and registers a resource file indicated by the resource file registration request, and transmits the registration result back to the member node initiating the resource file registration request. The at least one member node performs an operation on a real physical resource associated with the registered resource file by performing data communication with another member node.

Abstract: Embodiments of the disclosure provide a blockchain consensus method, apparatus, device, and storage medium and relate to the field of blockchain technology. The method includes determining, from a plurality of sub-blockchains, a target sub-blockchain to which a target block belongs, and adding the target block to the target sub-blockchain, where the target block is generated based on transaction data or obtained by synchronizing with other nodes; obtaining, from the plurality of sub-blockchains, a sequence of valid blocks for each of the plurality of sub-blockchains, where each sequence of valid blocks includes at least one valid block; and globally ranking the obtained valid blocks based on a logical clock corresponding to each of the obtained valid blocks, to obtain a global blockchain.
